• Operation Code — System software that is executed after boot-up,
also known as run-time code. This code runs the switch operations and
provides the CLI, Web and SNMP management interfaces. See
“Managing Firmware” on page 3-21 for more information.
• Diagnostic Code — Software that is run during system boot-up, also
known as POST (Power On Self-Test).
Due to the size limit of the flash memory, the switch supports only two
operation code files, and two diagnostic code files. However, you can have
as many configuration files as available flash memory space allows.
In the system flash memory, one file of each type must be set as the
start-up file. During a system boot, the diagnostic and operation code files
set as the start-up file are run, and then the start-up configuration file is
loaded.
Note that configuration files should be downloaded using a file name that
reflects the contents or usage of the file settings. If you download directly
to the running-config, the system will reboot, and the settings will have to
be copied from the running-config to a permanent file.
Configuring Power over Ethernet
The 24-Port Fast Ethernet PoE Switch’s 24 10/100 Mbps ports support
the IEEE 802.3af Power-over-Ethernet (PoE) standard that enables DC
power to be supplied to attached devices over the unused pairs of wires in
the connecting Ethernet cable. Any 802.3af compliant device attached to a
port can directly draw power from the switch over the Ethernet cable
without requiring its own separate power source. This capability gives
network administrators centralized power control for devices such as IP
phones and wireless access points, which translates into greater network
availability.
